We only use wireless on an iPad and two iPod Touches and occasionally on a Mac laptop. I have a WinXP desktop but on ethernet only without a wireless card, so that doesn't count.
Since about 10 days ago, we couldn't suddenly couldn't connect at all via wireless on the Mac laptop or any of the iPad/iPod devices and just kept getting a "unable to join the network" error. Thinking maybe the wireless part of the old NetGear DG834G router had broken down or something, I got a Billion 7800N router (with firmware 1.06c pre-installed), having read here how it's supposed to be the bee's knees even though I'm by no means a router "expert" and don't understand much of what some of you talk about , and installed it today.
But we still can't connect wirelessly... ethernet's fine on both the WinXP desktop and Mac laptop. The devices see the connection but the minute we try to connect, it still throws up a "unable to join the network" error.
I tried changing the channel from 11 to 1, made no difference.
I tried changing the security key from a WPA2 one to a WEP one, just to see. It worked. But I don't want to use the less secure WEP key. If the WPA2 key worked before, it should work OK now regardless of what router it is?
I tried contacting my ISP support, but they couldn't figure it out either - other than to suggest that the wireless card driver in the iPad needed updating!!! <slaps forehead>
Would anybody have any idea why we're having this problem, or if there's something else I should be doing to the Billion router as it has a "billion" more options than the NetGear one?
